To optimize the conditions for the extraction of panax notogingseng saponins (PNS).
After selected extraction solvent and suitable particle, we employed orthogonal experimental design to examine the conditions for the extraction by determination of PNS.
Significant effect was observed only in extraction times.
The optimum condition for extraction of PNS was to extract panax notogingseng (Burk.) F. H. Chen with 10 times 70% ethanol for 1.5 hours for 3 times.
